explain Planck's Quantum theory?
Answers
Planck's quantum theory. According to Planck's quantum theory, Different atoms and molecules can emit or absorb energy in discrete quantities only. The smallest amount of energy that can be emitted or absorbed in the form of electromagnetic radiation is known as quantum.
ANSWER
PLANCK'S QUANTUM THEORY
When a body is heated, it emits thermal radiations of different wavelengths or frequency. To explain these radiations, Max Planck put forward a theory is known as Planck's quantum theory.
The main points of quantum theory are:
⏺️Substances radiate or absorbs energy discontinuously in the form of small packets or bundles of energy.
⏺️The smallest packets of energy is called quantum. In case of light the quantum is known as photon.
⏺️The energy of a quantum is directly proportional to the frequency of the radiation.
⏺️A body can radiate or absorb energy in whole number multiples of a quantum hn,2hn,3hn.......nhn. Where 'n' is the positive integer.
⏺️Neils Bohr used this theory to explain the structure of atom.
